Processors for the Internet of Things
Pieter van der Wolf, Yankin Tanurhan · 2021
The Internet of Things (IoT) enables a “smart world” in which many billions of devices communicate to provide advanced functionalities. Many IoT edge devices are battery-operated and demand an optimized implementation in order to enable a long battery life. This chapter analyzes the compute requirements of IoT edge devices and discuss processor capabilities that support the efficient implementation of such devices. It presents concrete examples of versatile, configurable and extensible processors that provide capabilities for control processing, DSP (e.g. voice/audio processing, communications) and machine learning. The processor examples are complemented with benchmark data for illustrative IoT edge application functions. The common theme in machine learning is that algorithms that have the ability to learn without being explicitly programmed are used.
